7:53 PM | The Robots at the End of the World
By Melissa Mahony Remember the rovers, NASA’s Mars-trekking robots that have been roaming the red planet off and on since 2004? Well, here comes Grover, the space agency’s new unmanned, Earth-hugging vehicle, which is about to explore another remote, inhospitable place: Greenland’s ice sheet. Tomorrow, NASA will begin testing Grover -- short for Greenland Rover, or short for Goddard Remotely Operated Vehicle for Exploration and Research, take your […]

4:15 PM | Student-Designed NASA Rover Is An 800-Pound, Solar-Powered Tank
Designed by engineering students, the GROVER is about to start starting exploring the wilds of Greenland. Last year, satellite data showed 97 percent of Greenland's surface ice had turned to slush in unseasonably warm weather. NASA wants to study phenomena like that to learn more about why it's happening and the rate at which it's happening, but using satellites or radar-equipped planes can be costly. So this is the alternative: GROVER, an engineering student-designed, lumbering, […]

A little over 1000 years ago Eric the Red sailed around the southern tip of Greenland to set up the first successful European settlement in Greenland.  But it wasn’t just people and farm animals that joined Eric in his exile- seeds of several weedy plants likely stowed away on sheep fur and hay to become their species’ first representatives on the western coast of Greenland.  For decades

4:47 PM | How the Warming Arctic Affects Us All
On September 16, the extent of the Arctic Ocean’s ice cap reached a new low, breaking the previous record low set in 2007. Some scientists believe that, at this rate, the Arctic could be ice-free by 2030 or even earlier. The Arctic may seem remote, but the overall rate of global warming, our climate and weather, sea levels, and many ecosystems and species will be affected by the warming that is occurring there.
